# Administration

Capable Diagrams works with no configuration at all, which is the point. Everything on this branch is optional, and most sites change two or three things: the language list, a space display mode, and possibly a shape library.

The one rule worth learning first is where each setting lives, because a setting changed at the wrong level appears to do nothing.

## The three levels

| **Level** | **Who can change it**        | **Covers**                                                         |
| --------- | ---------------------------- | ------------------------------------------------------------------ |
| Site      | Confluence administrator     | Languages, shape libraries, global templates, egress, renderer, AI |
| Space     | Space administrator          | Rendering defaults for every diagram in the space                  |
| Macro     | Anyone who can edit the page | One diagram, overriding the space                                  |

ℹ️

**Start with space settings.** They fix the most common complaints, need only space admin, and are reversible without touching any page.
